Module: OpenHAB::CoreExt::Ephemeris

Included in:
Date, DateTime, Java::LocalDate, Java::MonthDay, Time
Defined in:
lib/openhab/core_ext/ephemeris.rb

Overview

Note:

openHAB’s built-in holiday definitions are based on bank holidays, so may give some unexpected results. For example, 2022-12-25 is not Christmas in England because it lands on a Sunday that year, so Christmas is considered to be 2022-12-26. See [the source](github.com/svendiedrichsen/jollyday/tree/master/src/main/resources/holidays) for exact definitions. You can always provide your own holiday definitions with holiday_file or holiday_file!.

Forwards ephemeris helper methods to ‘#to_zoned_date_time` provided by the mixed-in class.
